Here is one more achievement by India's Instrument Research and Development Establishment (IRDE),a lab of DRDO for developing the Laser Guided bomb tech from the scratch.

The development of technology for producing Laser Guided Bomb(LGB) is part of ongoing research towards achieving self-dependency in the defense area being done in IRDE, a lab of DRDO, Scientist and Public Relation Officer of IRDE told PTI.

LGB uses a laser designator to mark or illuminate a target. The reflected laser light from the target is then detected by the seeker which sends signals to the weapon's control surfaces to guide it towards the designated point, he said.
Bangalore-based Aeronautics Development Establishment (ADE) has developed the guidance-kit for 1000-pound LGBs and these are designed to improve the accuracy of air-to-ground bombing by IAF.

The guidance kit of LGB consists of a computer control group (CCG), guidance canards attached to the front of the warhead for providing steering commands and a wing assembly attached to the aft end to provide lift.

India had already carried out two successful flight trials of LGB for the IAF to test the effectiveness of the guidance and control systems at Chandipur integrated test range in Orissa early this year.

LGBs are manoeuvrable, free-fall weapons requiring no electronic interconnect to the aircraft and attack the target with higher accuracy and reliability.

The LGBs were first developed by USA in 1960s. Later, Russia, France and Britain also developed them.
